Book Description
Protecting and maintaining water distributions systems is crucial to ensuring high quality drinking water. Distribution systems-consisting of pipes, pumps, valves, storage tanks, reservoirs, meters, fittings, and other hydraulic appurtenances-carry drinking water from a centralized treatment plant or well supplies to consumers' taps. Spanning almost 1 million miles in the United States, distribution systems represent the vast majority of physical infrastructure for water supplies, and thus constitute the primary management challenge from both an operational and public health standpoint. Recent data on waterborne disease outbreaks suggest that distribution systems remain a source of contamination that has yet to be fully addressed. This report evaluates approaches for risk characterization and recent data, and it identifies a variety of strategies that could be considered to reduce the risks posed by water-quality deteriorating events in distribution systems. Particular attention is given to backflow events via cross connections, the potential for contamination of the distribution system during construction and repair activities, maintenance of storage facilities, and the role of premise plumbing in public health risk. The report also identifies advances in detection, monitoring and modeling, analytical methods, and research and development opportunities that will enable the water supply industry to further reduce risks associated with drinking water distribution systems.

Book Description
Twort's Water Supply, Seventh Edition, has been expanded to provide the latest tools and techniques to meet engineering challenges over dwindling natural resources. Approximately 1.1 billion people in rural and peri-urban communities of developing countries do not have access to safe drinking water. The mortality from diarrhea-related diseases amounts to 2.2 million people each year from the consumption of unsafe water. This update reflects the latest WHO, European, UK, and US standards, including the European Water Framework Directive. The book also includes an expansion of waste and sludge disposal, including energy and sustainability, and new chapters on intakes, chemical storage, handling, and sampling. Written for both professionals and students, this book is essential reading for anyone working in water engineering. - Features expanded coverage of waste and sludge disposal to include energy use and sustainability - Includes a new chapter on intakes - Includes a new chapter on chemical storage and handling

Book Description
Traditionally, indigenous irrigation in many countries of Asia, Africa, and Latin America has been managed quite well by water users, who design, build, operate, and maintain often sophisticated, but usually small-scale, systems. More recently, in connection with large-scale development programs and government-managed schemes, the planned introduct

Book Description
Introduction about what this manual is covering concentrating on Large Scale Irrigation (LSI), diversion barrage or weir, intake (with auxiliary structures), and most common conveyance structures suitable for LSI. A very brief overview of an approach to match water needs with water availability (demand vs supply) with references and links to Food and Agriculture Organization (FAO) literature that is covering the topic in detail. A brief reference to the most common methods to obtain necessary hydrological parameters for IRR scheme design. A very brief overview of the importance of knowledge of geological conditions and the investigation needed to obtain geotechnical design parameters (including the most common geotechnical tests to obtain design parameters). Planning phase considerations regarding diversion and intake structure, discussing the role of the main components. More technical discussion on each component of the weir or intake, including formula and worked examples (hydraulic and structural computations). Conceptual, hydraulic, and structural considerations of main conveyance components, with emphasis and more detail on most used components (such as canals, siphons, aqueducts, retaining walls, etc.). A very brief overview of the approach to irrigation water management and Operations & Maintenance (O&M), with references and links to FAO literature that is covering the topic in detail. Standard specification for irrigation construction material.
